Osmessagetrace is a potentially unwanted program that can reroute any user to different pages needing more visits. Osmessagetrace introduces to your browser a new search engine to execute this function and changes the URL of your homepage without requesting your approval.

Osmessagetracer Mac

The developers of Osmessagetrace promote it as a free Mac browser add-on that aims to improve the user’s web browsing experience and to include the best online deals in the search results. In fact, however, this software acts as a browser hijacker and takes over the main web browser without seeking permission, whether this is Safari, Chrome, Firefox or another browsing app.

Osmessagetrace for Mac

Osmessagetrace for Mac is a browser hijacking application that can substitute the user’s preferred search engine with a different one. Osmessagetrace for Mac may also change the default homepage URL to a specific one that is loaded when a new tab is opened.

The endless generation of pop-up advertisements, banners, random notifications and redirect links is a major source of irritation and a good reason for a lot of web users to seek methods to remove Osmessagetrace from their system. These advertisements not only tend to interrupt the web browsing by covering any website the users visit but they are also very difficult to remove and discourage users from making use of their web browser. The people who want to enjoy uninterrupted web surfing often have no alternative but to uninstall Osmessagetrace along with all the search engine and homepage improvements it has made. This, however, is a task that typically requires the assistance of a professional removal tool or a removal guide like the ones that you will find below.

What is Osmessagetrace?

Osmessagetrace is a browser hijacker that users can install in their Mac browser much like a standard extension. Programs such as Osmessagetrace are typically distributed via program bundling and are promoted as tools that enhance the web browsing experience. In reality, however, they initiate redirects to sponsored sites and spam the screen with ads.

Programs from the browser hijacker class are not really dangerous and are not expected to harm your computer the way that a ransomware virus or a Trojan horse can. However, their uninstallation can be a little difficult and only a professional removal tool can handle it quickly and without unnecessary risks for the system. This is because many hijackers tend to install additional components that help them to display their sponsored ads and to redirect users to particular pages and these components need to be carefully detected and removed so that the hijacker gets successfully uninstalled from the system.

The Osmessagetrace app

The Osmessagetrace app is a piece of software that normally does nothing harmful to your computer or the files you save on it. The main reason the Osmessagetrace app exists is to take advantage of all kinds of online advertisements and paying web promotions.

The fact that Osmessagetrace isn’t malicious, however, does not mean that malware such as Ransomware, Trojan or viruses cannot find their way inside your system through the hijacked browser. Normally, the danger may come from unsafe pop-up notices, banner ads and page redirect links that Osmessagetrace or Mictiotom may promote on your screen. With just one click on such a message or link, you may land on dubious web pages where you can be exposed to different viruses. Besides, the hijacker may often show reminders and warnings urging you to download and install potentially unwanted software or purchase some apps and products simply because clicking on that particular web ad or link generates the developers’ some money per visit.


TypeAdware/Browser Hijacker

SymptomsUnauthorized changes of the browser’s homepage and search engine can indicate the presence of a browser hijacker in the system.

If this does not help then continue reading this article for more detailed instructions on how to get rid of Osmessagetrace!


The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively, you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.



Start Activity Monitor by opening up Finder, then proceed to activity-monitor

Once there, look at all the processes: if you believe any of them are hijacking your results, or are part of the problem, highlight the process with your mouse, then click the “i” button at the top. This will open up the following box:


Now click on Sample at the bottom:


Do this for all processes you believe are part of the threat, and run any suspicious files in our online virus scanner, then delete the malicious files:

    First, Force Quit Safari again.

    Now if you are using a Wi-Fi connection turn it off by selecting Wi-Fi off in you Mac’s Menu. If you are using a cable internet (Ethernet connection), disconnect the Ethernet cable.


    Re-Launch Safari but don’t forget to press and hold the Shift button while doing it, so no previous pages can be opened up. Now, Click on Preferences in the Safari menu,

    Again select Preferences in the Safari Menu, but this time click on the Privacy tab,
